Accusize Industrial Tools 13 Pc 7/16'' to 1-1/16'' H.S.S. Annular Cutters, 2'' Cutting Depth, 3/4'' Weldon Shank, with 2 Pilot Pins, Strong Case, N2

These bits are very good. Make sure to use some cutting oil and turn slow.

I have purchased from Accusize multiple times, and never had issues at all. One of the bits in this kit had a random defect, it cracked and split when I used it. I emailed and asked if I could have a replacement for that bit. They replied within 30 minutes, apologized, and included a tracking number for the replacement bit. They have good products and great customer service. I won't hesitate to buy from them again.

Comme toujours, les outils Accusize répondent très bien à mes besoins, bien conçus et de très bonne qualité ainsi que précis... ne reste qu'à faire la job maintenant !!!

I've had to punch holes up to 9/16 wide and 3/4 thick. And so far no dulling from any of the bits.

Case that the bits comes in is kinda cheap, but the bits so far are great.
